Variances and covariances in inbreeding load are shown as calculated by repeated measures analysis of variance (SAS) using the best-fit covariance structure. Covariances are listed under the age classes being compared; e.g., “1, 1” is the variance of week 1, while 1, 2 is the covariance in inbreeding load between weeks 1 and 2. Asterisks indicate that a value is significantly different from zero at α = 0.05.
